On the USB charger, there will be text that indicates the amp (A) or milliamp (mA) rating of the charger. This rating varies among chargers – including those supplied with different models of Bose products. The closer the amp rating of the charger is to the maximum amp rating of the product, the more quickly the product will recharge. If the amp rating of the charger is too low, the product may recharge slowly or not at all. Refer to the specifications indicated on the product or within it's owner's guide on for details.

Some products require minimum of 1 amp of current in order to recharge. Many USB ports on a computers can only provide a maximum of 0.5 amps of current. Be sure to use a safety-agency-approved power supply that meets local regulatory requirements (e.g. UL, CSA, VDE, CCC).

Try connecting your product with a different USB cable to determine if there is an issue with the first cable.
